Experience
Rhea Software (UsableNet)
• Testing was performed on mobile applications (Android, iOS, Windows) using mobile and tablet devices, accessing web apps via different browsers, and the mobile web via mobile and tablet devices. Some of the clients have their own devices used for testing.
• The projects contained different types of industries such as airlines, booking hotels, eCommerce, online banking, insurance, customer services, and more.
• Special attention was paid to the testing web analytics depending on the client's business.
• Most of the projects were tested in different languages, e.g., Spanish, English, German, Portuguese, Italian, French, Chinese, Japanese, among others.
• For testing, we used real credit cards with different amounts to cover real use cases.
• This was an intensive collaboration with clients from all over the world.

Carnegie Technologies
• We tested the project on mobile (Android, iOS) and web apps (cross-browser) along with back-end testing (server and database).
• One project had apps based on VoIP and SIP. It allows a user to send voice/video messages via peer-to-peer multimedia, make calls using the internet, and create group chats/calls.
• Another project contained various components and types of apps (Android, iOS, web); we integrated these extras into one complex system. There are two client apps (Android & iOS), two administrator apps (Android & iOS), and one advanced administrator web app. The database which supports this whole system is very complex, and each app has several APIs supporting different methods. The app was very flexible because it gave the admin more choices. It had a login/register form, validation options (MDN, chat, and chatbots), and different permission groups; and an admin could assign any combination for a loyalty program.
• We also worked on another web app for building the entire organizational structure for any company. It creates a system where you can have different roles, permissions, schedule meetings, make notes and documents, upload/download files, leave comments, and have a chat.
